Application tiled March 27, 1899. Serial No. 710,605. (No model.)

To @ZZ whom, t may concern.-

Be it known that I, WILLIAM R. SALISBURY, a citizen of the UnitedStates, residing at Lamoni, in the county of Decatur and State of Iowa,have invented certain new and useful Improvements in Oultivators; and Ido hereby declare the following to be a full, clear, and eX- actdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to certain new and useful improvements incultivators.

The invention relates more particularly to that class of cultivatorsknown as lister cult-ivators, which are usually of the wheeled type andare adapted to straddle a row of corn or other plants around which it isdesired to embank the earth.

One of the objects of my invention is to construct a cultivator of thisclass which will be extremelysimple inits constructiomstrong,

durable, effectual in its operation, and com-l paratively inexpensive tomanufacture.

Another important object of the invention is to provide means forshifting the weight of the cultivator when desired to the rear of thesame in order that the turning of the same at the end of a row may beeasily accomplished.

A further object of my invention is to construct a cultivator of thisclass havingapair of adjustable moldboards and so arranged as to cut andturn the top of the soil and weeds, and thereby allow the adjustableshovels arranged at the rear of the adjustable moldboards and at areverse incline thereto to engage the clean soil and embank the samearound the corn or other plants.

Briefly described, therefore, my invention consists in a pair ofadjustable moldboards, a pair of adjustable shovels, together with apair of runners, and a suitable carriage for the aforementionedparts,together with means carried by the carriage for operating thetongue so as to shift the weight to the rear of the cultivator whendesired to turn the same.

The invention iinally consists in the novel construction, combination,and arrangement of parts to be hereinafter more specifically describedand then particularly pointed out in the claims.

In describing the invention in detail reference will be had to theaccompanyings, forming a part of this specification and wherein likeletters of reference will indicate similar parts throughout the severalviews,in which- Figure l is a perspective View of my improvedcultivator. Fig. 2 is a longitudinal sectional View of the same. Fig. 3is a perspective view of a portion of the tongue-operating mechanism,also showing a portion of the runners in dotted lines. Fig. 4 is aperspective view of the keeper in which the rear end of the tongueoperates.

To put my invention into practice, I provide a suitable frame which maybe composed of several pieces, or this frame may be cast in one piece,as may be desired, though in the illustration of my invention I haveshown the same as consisting of the side rails l, which at theirforwardends are connected to a cross-piece 2 and at their rear ends to asimilar cross-piece 3, the latter being mounted y upon and rigidlysecured to the axle 4. The

cross-piece 2 is rigidly bolted or otherwise secured to the runners 5,these latter being supported at their rear ends by the axle 4 and havingtheir forward ends enlarged or swelled, as shown at 6, which portion isadapted to contact with the soil. The front ends of the runners arepreferably rounded, as shown, to permit their readily passing over anyobstruction. These runners have pivotally attached to their outer faces,by means of bolts 7 or other suitable means, the moldboards 8, whichtaper downwardly on the forward end thereof and also project outwardlyfrom the runners in order that when the soil is cut thereby it may alsobe turned over in the same manner as is accomplished by an ordinaryplow-moldboard. These tapering moldboards are connected together attheir upper edge near the rear ends by means of a connecting-bar 9, andthey are made adjustable in order that they may be made to conform to aneven surface or to furrowed ground. This adjustment of the moldboards'is accomplished by providing each with an oblong aperture 10, which iscountersunk to receive the headof the securing-bolt 11, which engagesthe runner 6. The head of this bolt is countersunk in order that thesame may not extend beyond the outer face of the moldboard. When thisbolt is loosened, it will be observed that the moldboards may beadjusted to the posi- IOO tion desired, and when the bolt is tightenedit will hold the moldboards in this adjusted position.

In order to embank the soil around the row of corn-plants, I provide apair of adjustable shovels 12, which are inclined inwardly and arerigidly secured on the lower ends of the adjustable supporting-rods 14.These supporting-rods are curved, as shown, in order that the shovelsmay be adjusted to engage the soil to any desired depth, and the rodsare supported and retained in the desired position by means of keepers15, secured to the inner face of each of the side rails 1 and havingarranged therein set-screws 16, the inner ends of which contact with thesupportingrods. By loosening these set-screws the supporting-rods may beoperated within their keepers, so as to adjust the shovels in thedesired manner.

The tongue 17 is supported by a king-bolt 1S, engaging the same andacross-piece 19, rigidly secured to the upper face ofthe runners neartheir forward ends. The aperture 2O in the tongue for the reception ofthis kingbolt is made larger than the diameter of the king-bolt in orderto permit the vertical movement of each end of the tongue. The rear endof the tongue operates in aguide or keeper 21, oblong in form, andhaving two side lugs 22, by means of which the same maybe rigidlysecured to the upper face of the runners 6. For the purpose of obtaininga leverage against the rear end of this tongue and by this meansshifting the weight of the cultivator to the rear thereof in order tofacilitate turning I pivotally connect to one of the runners a lever 23,which hasy attached thereto the one end of a rod 24. The other end ofthis rod 2-1 is pivotally connected to the upwardly-extending end of thebell-crank 25, which is journaled in or supported by the runners at apoint at or near the end of the tongue. This bell-crank engagesunderneath the tongue and when the lever 23 is pulled backwardly raisesthe rear end of the tongue, drawing down the forward end thereof, andconsequently throwing or shifting the weight of the cultivator to therear part thereof. For the purpose of retaining the tongue in thisposition I attach to the lever 23 a spring-actuated rod 26, carrying inits lower end a pawl 27, adapted to engage the segment-shaped rack 2S,which may be secured either to the runner or to one of the side rails.By this arrangement and construction it will be observed that when theweight is thus shifted upon the wheels of the cultivator the moldboards,which constitute the plow, will be elevated, and the cultivator may beturned at the end of the row without these moldboards injuring theplants.

By the arrangement of the moldboards preceding the shovels the top ofthe soil, together with Weeds or obstructions, is removed in order thatthe reversely set or inclined shovels may engage the fresh and cleansoil and throw the same around the plants in the desired manner.

While the construction asheren shown and described appears to embody thepreferable form of my invention, yet I do not wish to unduly limitmyself thereto, but desire the right to make such changes as theomission or addition of parts or the substitution of equivalentstherefor as would clearly come within the scope of my invention.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is

1. In a cultivator of the class described, the combination of a frame, asupporting-truck, a pair of runners rigidly connected to said truck, apair of moldboards adjustably connected to said runners with their loweredge inclined outwardly and having their forward ends taperingdownwardly, and a pair of adjustable shovels carried by said frame andset at a reverse incline to the adjustable moldboards, substantially asdescribed.

2. In a cultivator of the class described, the combination of a frame, apair of runners rigidly connected to said frame, a pair of moldboardsadjustably connected to said runners and having their forward endstapering downwardly, an adjustable tongue, and means carried by saidframe for adjusting said tongue, substantially as described.

3. In a device of the character described, the combination of a frame, apair of adjustable shovels carried by said frame, a pair of runnersconnected to the frame, a pair of adjustable moldboards connectedtogether and supported from said runners, said moldboards having theirforward ends tapering downwardly and their lower edge inclinedoutwardly, an adjustable tongue, a keeper connected to said runners andadapted to receive the rear end of said tongue, a lever pivotallyconnected to one of saidrunners, and a bellcrank journaled in therunners and connected to said lever and adapted to engage said tonguefor operating the same, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
